Chinese Honey Locust

Gleditsia sinensis
Leguminosae (Pea family)
It is well worth searching out the Chinese Honey Locust to the west of the Systematic Beds, grouped amongst its relatives in the Pea family.
The trunk of this impressive tree is heavily armoured with clusters of ferocious, branched spines. This tree lost its champion status when its top was removed in order to maintain its structural integrity. Great Spotted Woodpeckers often nest in a hollow branch.
